Description

Technical Field

[0001] This utility model relates to the field of down spraying technology for composite knitted fabrics, specifically a down spraying device for composite knitted fabrics. Background Technology

[0002] In the process of processing composite knitted fabrics, an adhesive needs to be sprayed onto the surface of the knitted fabric. Then, a spray-type fabric flocking machine uses high voltage electrostatic charge to give the flocking fibers a negative charge, causing them to fly up and adhere to the surface of the object coated with adhesive under the action of an electric field, forming a flocking effect with a strong three-dimensional effect and a soft hand feel. This is suitable for small-batch or customized production.

[0003] Some nozzle-type fabric flocking machines require manual control of the nozzles during use. While this method offers flexibility and precision in certain aspects, it also presents some inconveniences. For example, manual control requires the operator to constantly move and adjust the nozzle position, which significantly reduces work efficiency in large-area flocking operations. Furthermore, manual operation can easily lead to uneven or missed flocking of the fabric, affecting the quality of the fabric processing.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing composite knitted fabric spraying devices. Utility Model Content

[0005] The purpose of this invention is to provide a flocking device for composite knitted fabrics, in order to solve the problem mentioned in the background art that requires the operator to constantly move and adjust the position of the nozzle for manual control of the nozzle, which will significantly reduce the work efficiency in large-area flocking operations. In addition, manual operation is also prone to uneven or missed flocking of the fabric, which affects the quality of fabric processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a down spraying device for composite knitted fabrics, comprising a mobile frame and a controller fixedly mounted on the mobile frame. A storage tank is fixedly mounted on the mobile frame, and a flexible hose is connected through the top of the storage tank, with a nozzle installed at the end of the flexible hose. A support frame is fixedly connected to the side of the mobile frame, and a fixed frame is fixedly fitted on the support frame. A steering shaft is rotatably connected to the fixed frame, and a mounting seat for mounting a limiting nozzle is provided in the steering shaft. An autonomous drive mechanism is provided on the support frame to drive the mounting seat to reciprocate and rotate to expand the down spraying range.

[0007] Preferably, a guide tube is fixedly connected through the mounting base, and a locking post is fixedly connected to the outside of the nozzle, with the locking post engaging in the guide tube.

[0008] Preferably, the autonomous drive mechanism includes a sliding tube that is laterally slidably connected to the support frame, a transmission rod that is rotatably connected to the sliding tube, and the transmission rod that is rotatably connected to the mounting base.

[0009] Preferably, a workbench is fixedly installed on the support frame, and a heating plate for placing and transmitting composite knitted fabric is fixedly installed on the workbench. Multiple heat conduction grooves are evenly spaced on the heating plate. A heating mechanism is provided below the workbench to uniformly provide heat to the heating plate.

[0010] Preferably, the heating mechanism includes a slide rail fixedly installed on the inner wall of the heating pool, a slide seat slidably connected to the slide rail, a slide platform fixedly installed on the slide seat, and multiple heating tubes fixedly installed at equal intervals on the slide platform.

[0011] Preferably, a movable support is fixedly connected between the slide table and the sliding tube, and the movable support is slidably connected through the heating pool.

[0012] Preferably, an electric telescopic rod is fixedly installed in the heating pool, and an internal rod is fixedly connected to the output end of the electric telescopic rod. The internal rod is fixedly installed in the slide table. A fan blade is rotatably installed in the heating pool. A gear is fixedly sleeved on the fan blade along the direction of the rotation axis. A rack is meshed next to the gear and is fixedly installed on the internal rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the spray nozzle of the composite knitted fabric can be used manually or in combination with the mounting base. The spray process is uniform through the transmission of the mounting base, which does not require manual operation and has high spray processing accuracy.

[0014] Furthermore, the support frame is equipped with an autonomous drive mechanism that drives the mounting base to reciprocate and rotate to expand the spraying range. When the nozzle and mounting base are used together, the reciprocating rotation of the mounting base can be controlled by the sliding tube and transmission rod. The mounting base drives the nozzle to reciprocate and rotate, expanding the spraying range of the nozzle, maintaining the uniformity of the fabric spraying process, and making the process labor-saving and highly accurate.

[0015] Furthermore, a heating mechanism is installed below the workbench to uniformly provide heat to the heating plate. The fabric is placed on the heating plate and directionally transported to complete the spraying process. During processing, heat is generated by the heating tube to heat the fabric, so that the sprayed fabric and the fabric can be quickly solidified and connected. The slide table is controlled to move back and forth to expand the heating range of the heating tube. At the same time, the fan blades are driven to rotate to accelerate the gas flow, so that the gas can be quickly transferred to the heating plate and the fabric surface, thereby improving the quality of the fabric spraying process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-3 The present invention provides the following technical solution: a down spraying device for composite knitted fabrics, comprising a mobile frame 1 and a controller 2 fixedly mounted on the mobile frame 1. A storage tank 3 is fixedly mounted on the mobile frame 1, and a flexible hose 4 is connected through the top of the storage tank 3. A nozzle 5 is installed at the end of the flexible hose 4. A support frame 6 is fixedly connected to the side of the mobile frame 1. A fixed frame 7 is fixedly fitted on the support frame 6. A steering shaft 8 is rotatably connected in the fixed frame 7. A mounting seat 9 for mounting and limiting the nozzle 5 is provided in the steering shaft 8. An autonomous driving mechanism is provided on the support frame 6 to drive the mounting seat 9 to reciprocate and rotate to expand the down spraying range.

[0027] Please see Figures 3-5A guide tube 91 is fixedly connected through the mounting base 9, and a locking post 92 is fixedly connected to the outside of the nozzle 5, which is engaged in the guide tube 91. The autonomous drive mechanism includes a sliding tube 10 that is laterally slidably connected to the support frame 6, and a transmission rod 11 is rotatably connected to the sliding tube 10, which is rotatably connected to the mounting base 9.

[0028] During the spraying process, manual operation or mechanical processing can be selected. When operating manually, the nozzle 5 is held to the outside to control the spraying of the nozzle 5 onto the fabric surface to complete the processing. When processing mechanically, the locking pin 92 on the nozzle 5 is inserted and engaged in the guide cylinder 91, so that the nozzle 5 is mounted on the mounting base 9, limiting the position of the nozzle 5. The fabric is placed on the worktable 12 below for conveying. During the movement of the fabric, the nozzle 5 sprays the spray onto the fabric surface to complete the processing.

[0029] During the processing, the sliding tube 10 is controlled to move back and forth. At this time, the two ends of the transmission rod 11 connected between the sliding tube 10 and the mounting base 9 rotate. The rotating transmission rod 11 can drive the mounting base 9 and the steering shaft 8 to rotate back and forth, thereby expanding the spraying range of the nozzle 5 on the mounting base 9 and maintaining the uniformity of the fabric spraying process.

[0030] Example 2: Please refer to Figure 6 and Figure 7 Based on Embodiment 1, a heating mechanism is also disclosed, the specific structure of which is as follows: a workbench 12 is fixedly installed on the support frame 6, a heating plate 13 for placing and transmitting composite knitted fabric is fixedly installed on the workbench 12, and multiple heat conduction grooves 14 are equally spaced on the heating plate 13; a heating mechanism is provided below the workbench 12 to uniformly provide heat to the heating plate 13.

[0031] Please see Figure 6 and Figure 7 The heating mechanism includes a slide rail 16 fixedly installed on the inner wall of the heating pool 15, a slide seat 17 slidably connected to the slide rail 16, a slide table 18 fixedly installed on the slide seat 17, and multiple heating tubes 19 fixedly installed at equal intervals on the slide table 18. A movable bracket 20 is fixedly connected between the slide table 18 and the sliding tube 10, and the movable bracket 20 is slidably connected through the heating pool 15.

[0032] Please see Figure 8 An electric telescopic rod 181 is fixedly installed in the heating pool 15. An internal rod 182 is fixedly connected to the output end of the electric telescopic rod 181. The internal rod 182 is fixedly installed in the slide table 18. A fan blade 185 is rotatably installed in the heating pool 15. A gear 184 is fixedly sleeved on the fan blade 185 along the direction of the rotation axis. A rack 183 is meshed next to the gear 184. The rack 183 is fixedly installed on the internal rod 182.

[0033] During processing, the fabric is placed on the workbench 12, and the fabric movement is controlled by the winding equipment at both ends. Heat treatment plays a key role in the down spraying process, mainly used to cure the adhesive and ensure that the pile adheres firmly to the base fabric. The heating tube 19 in the heating tank 15 generates heat, which is transferred upward through the heat conduction groove 14. The heat is absorbed by the heating plate 13 and the fabric, which helps the pile on the fabric surface to be quickly cured and confined to the fabric surface during the down spraying process.

[0034] The electric telescopic rod 181 drives the built-in rod 182 and the slide table 18 to move back and forth. The two sides of the slide table 18 move along the slide rail 16 via the slide base 17. When the slide table 18 moves back and forth, it can expand the heating range of the heating tube 19 and keep the heat distribution uniform. At the same time, the slide table 18 drives the sliding tube 10 to move back and forth synchronously via the moving bracket 20, which provides power to the sliding tube 10 and can drive the nozzle 5 to rotate back and forth.

[0035] When the slide table 18 moves back and forth, the rack 183 meshes with the gear 184 and moves back and forth. Under the meshing transmission, it can drive the fan blade 185 to rotate, which can accelerate the gas flow in the heating pool 15 and keep the heat evenly distributed in the heating pool 15, so that the fabric is evenly heated and the pile is cured during the spraying process.
